BLACKING-BOX OR THE LIKE.

Specification of Letters Patent.

Patented Oct. 15,1912.

Application filed January 31, 1912. Serial No. 674,509.

To all whom it may concern:

Be it known that 1, CHARLES STUPIAN, a subject of the King of Hungary,residing in Bufialo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Blanking-Boxes or the Like, ofwhich the following is a specification.

My invention relates to blacking boxes or the like and particularly tomeans for separating .the two parts of the box or other receptacle inwhich the invention may be embodied. v

Blacking boxes and other receptacles usually consist of a holding orcontaining part, and a lid or cover applied to the holding or containingpart by a frictional fit in a manner to exclude air, either for thepurpose of preventing drying out of the contents, to prevent thecontents from becoming moldy, or to prevent the cover from beingaccidentally removed and the contents spilled; depending, of course, onthe nature of the contents.

While my invention is particularly designed for blacking boxes it isapparent from the foregoing that it may be embodied in various otherreceptacles. It is'very desirable to have air-tight covers on blackingboxes, not only during shipment or while stored, but also during thetimes of their be ing used, as blacking boxes are frequently opened andclosed before the contents are entirely consumed. The frequent openingof the box is annoying and difficult when tight fitting, which it shouldbe to exclude air from the contents until entirely used. This annoyanceand difficulty is entirely eliminated by the use of my invention, whichhas for its primary object the provision of a box or receptacle having atight fitting cover and being provided with means for quickly and easilyremoving the cover from the body of the box or receptacle.

My invention consists in the novel features of construction to behereinafter described and more particularly pointed out in the subjoinedclaims.

In the accompanying drawing I have shown my invention embodied in what Inow consider its most approved form, but it will be clear from thedetailed description following that changes may be resorted to withoutdeparting from my invention or sacrificing any of the advantagesthereof.

Figure 1 is a side elevation of a blacking box constructed according tomy invention, the cover being shown in fully closed or normal position.Fig. 2 is a similar view with the cover partly lifted on the body of thebox. Fig. 3 is a cross-section taken on line 3 3, Fig. 2. Fig. 4: is aplan view, and Fig. 5 is a detached perspective view of the coverlifter. 7

Referring now to the particular embodiment of my invention shown, Arepresents the body or holding portion of the box and B the cover whichfits tightly onto the upper marginal portion of the cylindrical sidewall of said holding portion, the extent to which it may be forced onthe said side wall being limited by an annular external bead a againstwhich the edge of the cover is adapted to bear when closed upon the bodyportion.

0 designates a second annular external bead on the body-portion which isseparated from the bead a by an intervening space, forming a groove (Z.While this groove is formed by means of the two external beads on thecylindrical wall of the body-portion it is clear that it may beotherwise formed so long as it serves the purpose for which it isintended.

6 represents a cover lifter which is preferably formed of wire circledaround the body of the box and entered into the annular groove (Z, saidlifter having an outstanding arm 9 by means of which it can be givenpartial rotary movement on the body-portion of the box and an upstandingengaging stud h. The wire from which this lifter is formed is preferablybent upon itself at one end, as at 2', to form two members lying incontact which constitute the outstanding arm g, one of said membershaving an upturned terminal which is also one of the terminals of thewire and forms the engaging stud 71. From the inner end of the othermember of said arm the wire is curved into circular form to fitaroundthe box, as at k, and the other terminal of the wire is twisted aroundthe arm 9, as at Z.

The cylindrical wall of the cover has a fixed inclined projection oroutstanding cam m formed by providing said wall with an outstandingelongated bead inclined with respect to the edge of the cover, the underside of said bead being adapted to be engaged by the stud h when turningthe lifter on the body-portion of the box. Slight force applied to thearm 9 of the lifter, after it has engaged the cam on the cover, willcause the cover to be raised from the bodyportion of the box and at thesame time loosen therefrom so that the cover can be easily removed.

In applying the cover it is merely necessary to see that the cam mthereon is out of line with the upstanding stud h of the lifter so thatthe cover can be forced tightly on the body-portion.

While I have shown the cam formed by beading the cover as described, itis clear that it may be otherwise formed on or applied to the cover.

Having thus described my invention, what I claim is 1. A receptaclecomprising a body-portion having an annular groove, a cover having anoutstanding inclined elongated projection, and a cover lifter having acircular portion rotatably fitting into said groove, an outstanding armand an upstanding stud adapted to engage said inclined projection on thecover.

7 2. A receptacle comprising a body-portion having an annular groove, acover having an inclined elongated projection on' itscircularrside'wall, and a cover lifter formed of .wire curved to providea circular port-ion fitting into said annular groove and bent having acircular portion fitting into said 1 groove, an outstanding arm and astud arranged at an angle to said arm adapted to engage said lncllnedpro ectlon.

In testimony whereof, I have aflixed my signature in the presence of twosubscribii.
